Reduce interpolation filter search

1. Do interpolation_filter_search after compound mode search.
This can skip interpolation_filter_search if compound_type_rd
is early terminated and should have more accurate interp_filters
decision.
2. Add early stop conditions in interpolation_filter_search.

Tested foreman, city, student CIF (30 frames, bitrate=500, Speed 1),
it is about 3.3% speed up and the average coding gain is about 0.25%.
